Central Dogma of Molecular Biology Flow of information
DNA macromolecule of information
DNA DNA Structure/function Structure/function - -
DNA Structure/function – Eukaryotic packing
DNA Replication 5’ to 3’
Figure 10.6 Transcription of a Eukaryotic Gene (Part 2) DNA -> RNA
RNA Structure/function mRNA – messenger RNA 5’cap polyA tRNA – transfer RNA
DNA Transcription and Translation The Protein Code ( Translation of RNA to Amino Acids)
DNA Transcription and Translation
Protein Structure/function
Protein Structure/function Sickle Cell Anemia Single nucleotide mutation changes protein code, changes protein shape and function
Protein Protein function function Form defines Function: Enzymes – catalyze reactions by lowering activation energy Structural- collagen, keratin, etc Storage – act as a reservoir of amino acids – ovalalbumin Antibodies – immune system ability to pin point antigens Hormones – signaling molecules that travel long distance in the body Contractile – myosin, muscle fibers
Protein Enzymatic Pathways Carbs, fats, proteins
DNA Technology – Extraction/Isolation Scale to fit your application Ethanol Extraction – quick/crude, damaged DNA, but can work with it Phenol-Chloroform – laborious, but high quality DNA Animation of Fugu Fish Extraction Spin Columns – quick and easy, use resin to isolate DNA
DNA Technology – Restriction Enzymes Endonucleases Restriction site Palindrome
DNA Technology - Amplification Polymerase Chain Reaction (PCR) PCR Animation
DNA Technology - Cloning Restriction Enzyme PCR Product
DNA Technology - Sequencing Capillary Electrophoresis Illumina – highly parallel Ion Torrent
DNA Technology - Sequencing Pacific Biosciences Oxford Nanopore
Protein Technology – Production Price Per Gram Prices in US Dollars * As of 4/4/2012
Protein Technology – Production Production is constrained by the organism we use to produce the protein in. We are constrained in part by the choices of history and the momentum of technology.
Protein Technology – Chromatography • Ion Exchange (protein charge) • Size Exclusion (separates on size) • Hydrophobic Interaction (hydrophobicity) • Affinity: • Protein A tail of Antibodies • His-tagged metal complexes (Ni) • Glutathione-s-transferase glutathione
